Clarissa Luxton


Clarissa joined Carpmaels & Ransford in 2018 as part of the Pharmaceuticals and Chemistry & Materials teams. Her work spans both these groups and she handles a wide variety of subject matter ranging from NCEs, medical uses and formulations, through to polymorphs and consumer products.

Clarissa has gained experience in drafting and prosecuting patent applications and has been involved in various European Patent Office oppositions and appeals for a number of marketed products. She also deals with global prosecution of patent applications, handling numerous global patent portfolios and developing and coordinating central prosecution strategies to bring these applications through to grant.

Before joining the firm, Clarissa graduated from University of Oxford with a first-class degree in Chemistry, having been awarded multiple scholarships from Balliol College in recognition of her academic achievements. Clarissa’s final year Master’s project focussed on using ultra-high performance liquid chromatography coupled to mass spectrometry to investigate changes in the metabolism of an LN18 glioblastoma cell line, with and without a transfected isocitrate dehydrogenase 1 (IDH1) mutation, when exposed to the biguanides metformin and phenformin.

Outside of work, Clarissa has a keen interest in food, travel and learning new languages. She also particularly enjoys all water sports, especially slalom water-skiing.
